Abstract

A gestão dos resultados das atividades agropecuárias tem se tornado um constante desafio para os empresários rurais e a sua mensuração é imprescindível para o planejamento e análises de desempenho. No caso do mercado do boi gordo não tem sido diferente, principalmente, no que se refere às oscilações apresentadas nos preços. Nesse sentido, o mercado futuro tem se traduzido em um importante instrumento para reduzir os riscos de oscilação de preços. Porém, o pecuarista precisa identificar qual a proporção da produção que deve ser protegida. Assim, o objetivo principal do presente estudo consiste em estimar a razão ótima de hedge (ROH) para os pecuaristas da região de Cuiabá/MT e Campo Grande/MS utilizando o Mecanismo de Correção de Erros (MCE) para os dados diários, semanais e mensais. Os resultados mostraram que a razão ótima de hedge é muito sensível a freqüência dos dados. A Região de Campo Grande/MS apresentou ROH superiores as de Cuiabá/MT, pois regiões com maiores volatilidades devem proteger uma parcela maior da produção. Além disso, concluiu-se que a razão ótima de hedge apresenta melhores índices quanto se insere o Mecanismo de Correção de Erros no processo de estimação confirmando que séries não estacionárias podem fornecem estimativas errôneas da razão ótima de hedge, quando não considerado as relações de co-integração entre as variáveis.----------------------------------------------The management of the results of the farming activities has if become a constant challenge for the agricultural entrepreneurs and its measure is essential for the planning and analyses of performance. In this case of the market of the fat cattle it has not been different, mainly, as for the oscillations presented in the prices. In this direction, the futures market if has translated an important instrument to reduce the risks of price fluctuation. However, the producer needs to identify to which the ratio of the production that must be protected. Thus, the main goal of the present study consists of esteem the Optimal Hedge Ratio (OHR) for the producer of the region of Cuiabá/MT and Campo Grande /MS using the Error-Correction Mechanism (ECM) for the daily, weekly and monthly data. The results had shown that the Optimal Hedge Ratio is many sensible the frequency of the data. The Region of Campo Grande/MS presented high OHR of Cuiabá/MT, therefore regions with higher volatile must protect a bigger share of the production. Moreover, concluded that the OHR presents better index how much the Error Correction Mechanism in the process of esteem is inserted confirming that not stationary series can supply mistaken estimates of the OHR, when not considered the relations of co-integration between the variables.
